Dr. Luke recounts his 70km, Sam learns what rawdogging means and Fran laughs at them both.

Fran also does some more running, Sam tries bicarb - again - but properly this time, and Luke talks about another down week or two.

Sam also reveals he has been accepted to be part of the PUMA Project 3 - which Fran finds very funny given a recent conversation they had - so will be 'treated like a pro' and given a cash incentive to break his marathon PB at London in April - enjoy!
